STEAM-GENERATO R.

SPECIFICATION forming part of Letters Patent No.3l1,395, dated January 27, 1885.

Application tiled April 18, 1884.

To all whom it may concern.-

Be it known that I, ANDREW WELTE, a citizen of the United States, residing at Atchison, in the county of Atchison and State of Kansas, have invented certain new and useful Improvements in Steam-Generators, of which the following is a description.

This invention relates to that class ofsteamgenerators used on farms for cooking feed for stock and it has for its object to produce a great amount of steam relatively to the amount of fuel consumed, and economy in the cost of the generator.

To this end my invention consists in the construction and combination of parts forming a steam generator, hereinafter described and claimed, reference being had to the accompanying drawings, in which Figure l is a front elevation of my steamgenerator and a cookingtub. Fig.2 is acen tral vertical section of the same, and Fig. 3 is a horizontal section at a: :r of Fig. 2, looking upward.

A represents the outer shell of the boiler, secured to a base, K, and provided with an inverted conical top, L.

B represents theinner shell of the boiler,having an inverted conical top, L, and serving as the combustion'chamber.

Gis thedoorthrough which fuel is admitted. N is the fire-grate, O the ash-pit, and P P the pit-doors.

F is the smoke-flue communicating with the fire-box through the outer and inner shells of the boiler. Water being poured into the c0nical top L is admitted to the boiler whenever the internal pressure is sufficient to raise the ball-valve Q, thus preventing any danger of explosion from low water, it being only neces- (No model.)

sary to first water the boiler cold, and after- 40 ward see that a supply of water is in the receptacle L.

O is a pipe connected with the apex of the inverted cone L, and extending down to the annular space within the boiler near its base. 45 By this means the fresh water is admitted directly to the lowest part of the boiler, so as to insure a thorough circulation, and this fresh water is to some extent heated in the conical receiverbefore entering the boiler.

H represents water-pipes located within the GOLHbUSlJlOILChELIIlbQI, and each connected with the interior of the boiler at four points, two of which are higher than the other two, thus insuring a circulation of water in them and subjecting the water to intense heat.

M represents a barrel in which the feed to be cooked is placed, and l is a pipe attached to the boiler at D to conduct steam from the boiler into the barrel to do the cooking. The cone L insures the keeping of water on the hottest part of the combustion-chamber.

What I claim as my invention, and desire to secure by Letters Patent, is

In a boiler, the combination, with the outer shell,A,shaped with its top L like an inverted cone and its body a vertical cylinder, and the shell B within the shell Aforming an annular space between the two shells, of the tube 0, extending from the apex of the conical top L 70 into the said annular space, and a self-closing ball-valve, G, substantially as shown and de scribed, for the purpose specified.
